Between 16.33 and 16.35 hours on 20 Jan 1943, U-453 fired four torpedoes at the convoy KMS-7 about 30 miles west of Cape Ténès and heard three detonations and one ship sinking. The only ship hit was the Jean Jadot (Master J. Prié) which sank after 15 minutes. The ship carried 80 crew members (36 Belgians), 19 officers and 304 ratings of the British Army and 11 gunners. Six crew members and nine soldiers were lost. 250 survivors were picked up by HMS Verity (D 63) (LtCdr R. Horncastle, RN) and the remaining men by the French trawler Duguay-Trouin.
